Theodore Roosevelt,
Professionalism in Sports
“ With very few exceptions the man who makes some athletic pursuit his main business, instead of turning to it as a health-giving pastime, ceases to be a particularly useful citizen. Of course I do not refer to the men who act as trainers and instructors at the different colleges and clubs ; these perform a most useful and honorable function, and among them several could be named who have rendered as high service as any men in the community. But the amateur athlete who thinks of nothing but athletics, and makes it the serious business of his life, becomes a bore, if nothing worse. ”
